These slots are preferably offset, relatively to each other, whereby are formed shoulders or stops 1, lc, against which. the arm 3V abuts when returned to the neutral position. By oscillating the arm 3 on its pivot 3b, it may be thrown from one slot into the ,other slot.

1d, 1d, indicate plates cast or formed with cutaway portions which, when placed side by side, define the walls of the .slots la. These plates may be secured upon the body l in relative position to each other by screws or bolts.

le indicatesl a vertical wall carried by one 'of said plates 1d, and extending longitudinally thereof adjacent to its cutaway por-V tion. This wall 1e operates to prevent cush- Y ably comprise a vertically arranged plate' 4ta, which is preferably formed integral with 'one of the plates 1d, and a releasing mechanism 4b coperating with the plate 4t to permit the movement of the arm 3 from one slot to the other. The release mechanism 4b may consist of a lever 4 pivotally mounted near the handle of the arm 3, a release pin 4d carried by the arm 3, and a connection 4e between the lever 4 and the release pin 4d. 1t will be understood that the plate 4 is arranged in juxtaposition with reference to the arm 3 so that when the latter lies in one slot 1l1 in neutral position,."-'the release pin 4d engages with ond-face of the plate 4a, and when the arm 3' is in the other slot l2l in neutral position', the release pin 4d engages with the opposite face of the plate fla. By operating the release lever 4the release pined is Ilfted above the free end "of the plate-4, whereby the arm 3 may be thrown from one slotv to the other.

5 indicates a support or bracket member provided with tWo feet 5El near the end adjacent to the arm 3. This plate is preferably arranged below t-he frame of the Vehicle body 1, and adjacent to the slots la.

6EL indicates a plate or latch member carried by .the shaft 6.

6b indicates a-pin for securing the plate to `the shaft. The free end of the plate or latch member is curved laterally to form a. latch 6c which engages with the arm 3. i

6d indicates a stop carried by a foo-tL for limiting the throw of the latch member.

3d indicates a recess formed in the arm 3, into which recess the latch 64 projects to lock the-arm 3 in neutral position. The plate 6a is preferably arranged between the feet 5a and has bearing engagement therewith whereby the shaft 6 is locked against axial movement.

7 indicates an arm preferably carried by the plate or support 5 at that end opposite to the feet 5a. v v

8Il indicates a locking mechanism mounted within the casing 8. 1

8b indicates a coupling member forconneet-ing the movable part of theflocking mechanism with the rock. shaft 6. This coupling member preferably comprises a `sleeve 8 into which the adjacent end of the rock shaft 6 slidablyvits. The sleeve Sc may pin 6d 'carried by the shaft 6. The locking mechanism 8a is controlled by a suitable key which fits the key-hole or opening 8e.

Detail illustration and description of the locking mechanism is 'omitted as it will. be

be formed with a slot 8d which receives aunderstood vthat any form of lock or locking device which is operated by an individ'ual key, may be used.

The form of locking mechanism illustrated is preferably a Yale lock as that construction of lock cannot be operated'by a pass Y key.

It will be understood that my invention permits the `person running thecar to lock the controller or operating arm or lever so that he can leave the car or vehicle in public 8', the shaft 6 is rocked in its bearings and.

throws the latch 6c into the recess 3d of theJ arm 3; and that by operatingpthe locking mechanism in the opposite directiom the latch 6 disengages the arm 3 whereby the latter is free to move forwardly and'backi-g wardly in the slots .l.

9 indicate 'devices which prevent the operation of the latch 6c at any time except These devices preferably comprise a pair of curved plates preferably formed integral' with and extending from oppositesideslof the arm 3. These devices are arranged 'in position to be engaged by the latch (icin case the latter is operatedv while the arm 3 '90 when the arm 3 is in 4neutral position.` t

is forward or backward of its neutral position. By this constructiouand arrangement. .it will be understood that the latch 6cl is maintained out of the path of movement-ofioo A the arm 3 in case the key-locking mechanism.

is operated for any reason while the arm 3 is in either forward o-r backward operative position. i

10 indicates means for preventing the ringing of the bell. These means preferably form part of an electric bell circuit-and l comprise a stationary contact 10, a yieldable contact 10b normally engaging the edntact 10, and a contact breaker 6e. This contact breaker 6e is preferably carriedjby the rock shaft 6 and en ages with the 1noV. able contact 10b when t efOrmer is rocked into locking position. The movable contact 10b preferably comprises a'liat spring having an inclined arm with which the breaker 6e engages to disconnect it from the con' tact 10a. `10c1 indicates a support of insulated material for the contacts 10, 10b. This support is providedv with suitable contacts 10e to which the wires of the bell circuit are connected. locking engagement with the arm 3, the contact breaker 6e separates the contacts l0', l0b and thus breaks the bell circuit. It will, therefore, be understood from the foregoing description, that whenV the Vehicleis left standing and its operating arm or lever -3 When the latch is thrown into noaoia is locked, the bell circuit is simultaneously broken by the operation of the arm-locking devices. Under these conditions the bell cannot be rung or tampered With While the car or vehicle isnot in use. When the arm "B is unlocked, the bell circuit is automatically closed by the spring operated contact 10".

To those skilled in the art of making devices of the class described, many alterations in construction and Widely ditering embodiments and applications of my invention will suggest themselves, Without departing from the spirit' and scope thereof.
